Occupational exposure to aerosols in two French airports: multi-year lung function changes.

As differential exposure to airport-generated aerosols may affect employee lung function, the main objective of this study was to longitudinally evaluate spirometry measures among Air France employees. In addition, an exploratory exposure assessment to airport aerosol was performed in a small cohort of workers using personal monitoring devices. Change in lung function over a ~6.

Pharmacometabolomics applied to low-dose interleukin-2 treatment in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease. The immunosuppressive functions of regulatory T lymphocytes (Tregs) are impaired in ALS, and correlate to disease progression. The phase 2a IMODALS trial reported an increase in Treg number in ALS patients following the administration of low-dose (ld) interleukin-2 (IL-2).

Randomized double-blind placebo-controlled cosmetic trial of a topical first-in-class Neutraligand targeting the chemokine TARC/CCL17 in mild-to-moderate atopic dermatitis.

Background: Atopic dermatitis has a marked economic impact and affects the quality of life. A cosmetic compound with an innovative strategy is proposed here as a small chemical neutraligand, GPN279 (previously identified as a theophylline derivative), that binds and potently neutralizes the TARC/CCL17 chemokine, activating the Th2 cell-expressed CCR4 receptor.

Objective: Our objective was to evaluate the safety and activity of topically applied GPN279 in mild-to-moderate atopic dermatitis patients in a randomized, double-blind, placebo-controlled, parallel group trial.

Change in cardiorespiratory parameters following surgical correction of pectus excavatum: protocol for the historical-prospective HeartSoar cohort.

Introduction: How cardiorespiratory function changes following the surgical correction of pectus excavatum (PE) often gives mixed results, with meta-analyses demonstrating no benefit in terms of pulmonary function but improvement in cardiac function. Functional responses may depend on type of surgery, follow-up time and/or the patient's presurgical functional status, and debate persists on the purely aesthetic nature of such surgery. The aim of this protocol is to analyse data describing lung function and incremental exercise testing before vs after the surgical correction of PE.

Sputum-Rheology-Based Strategy for Guiding Azithromycin Prescription in COPD Patients with Frequent Exacerbations: A Randomized, Controlled Study ("COPD CARhE").

(1) Background: We have previously shown that sputum rheology can discriminate between patients with COPD and other muco-obstructive lung diseases, and that it is correlated with mucin content and sputum eosinophilia. We now hypothesize that it could be a more-accurate guide than clinical evaluation for the prescription of azithromycin to prevent exacerbations of COPD and to reduce exposure to antibiotics; (2) Methods: "COPD CaRhe" is a multicentric, randomized, controlled trial comparing outcomes in two parallel arms (36 vs. 36 patients).

Standard patient training versus Vik-Asthme chatbot-guided training: 'AsthmaTrain' - a protocol for a randomised controlled trial for patients with asthma.

Introduction: Therapeutic education for patients with asthma has been shown to reduce asthma morbidity. The high availability of smart phones provides the opportunity to furnish patient training via specifically designed chatbot applications. The goal of this protocol is to perform a first pilot comparison of traditional face to face versus chatbot-guided patient therapeutic education programmes for patients with asthma.

Obesity in women with asthma: Baseline disadvantage plus greater small-airway responsiveness.

Background: Obesity is known to diminish lung volumes and worsen asthma. However, mechanistic understanding is lacking, especially as concerns small-airway responsiveness. The objective of this study was therefore to compare small-airway responsiveness, as represented by the change in expiratory:inspiratory mean lung density ratios (MLD , as determined by computed tomography [CT]) throughout methacholine testing in obese versus non-obese women with asthma.

Rheology predicts sputum eosinophilia in patients with muco-obstructive lung diseases.

Background: Mucus is known to play a pathogenic role in muco-obstructive lung diseases, but little is known about the determinants of mucus rheology. The purpose of this study is to determine which sputum components influence sputum rheology in patients with muco-obstructive lung diseases.

Methods: We performed a cross sectional prospective cohort study.

Did COVID-19 impact Positive Airway Pressure adherence in 2020? A cross-sectional study of 8477 patients with sleep apnea.

Background: Whether the COVID-19 pandemic impacts Positive Airway Pressure (PAP) adherence over the long-term is unknown and only preliminary short-term data have been reported.

Methods: With the aim of describing the impact of the first and second waves of COVID-19 on PAP adherence during 2020 in France, we designed a cross-sectional study of Sleep-Apnea (SA)-patients under PAP telemonitoring. To examine PAP adherence in adult SA patients, we assessed de-identified data from a non-profit healthcare provider database during the period January 1, 2019 to December 31, 2020.

Third-generation cognitive behavioral therapy versus treatment-as-usual for attention deficit and hyperactivity disorder: a multicenter randomized controlled trial.

Background: This study aims to compare improvements in attention deficit and hyperactivity disorder (ADHD) symptom severity between a group of ADHD children and parents undergoing a new therapeutic program based on third-generation cognitive behavioral therapy (Hyper-mCBT) and a similar group undergoing treatment-as-usual with the Barkley program.

Methods: Two hundred forty-eight children diagnosed with ADHD will be randomly assigned to either a Hyper-mCBT program or a Barkley program. This is a multicenter randomized (1:1), 2 parallel-group, superiority trial with evaluator blinding and stratification according to center and methylphenidate treatment.

Anti-interleukin 5 therapies failure criteria in severe asthma: a Delphi-consensus study.

Background: Current practices for assessing response to anti-interleukin 5/R treatment in severe asthma patients are heterogeneous. The objective of this study was to achieve an expert consensus defining failure criteria for anti-interleukin 5/R treatment in severe asthma patients.

Methods: Experts were invited to a 5-round Delphi exercise if they were pulmonologists managing ⩾30 patients at a nationally recognized severe asthma expert centre.

Health-related quality of life and disease progression in pulmonary arterial hypertension patients: a 3-year study.

Objectives: The role of health-related quality of life (HRQoL) and psychological variables in pulmonary arterial hypertension (PAH) progression remains poorly quantified. We aimed to investigate the relationship between disease progression in PAH patients and HRQoL and psychological characteristics.

Methods: A 3-year longitudinal cohort was initiated.

Complication and lung function impairment prediction using perfusion and computed tomography air trapping (CLIPPCAIR): protocol for the development and validation of a novel multivariable model for the prediction of post-resection lung function.

Background: Recent advancements in computed tomography (CT) scanning and post processing have provided new means of assessing factors affecting respiratory function. For lung cancer patients requiring resection, and especially those with respiratory comorbidities such as chronic obstructive pulmonary disease (COPD), the ability to predict post-operative lung function is a crucial step in the lung cancer operability assessment. The primary objective of the CLIPPCAIR study is to use novel CT data to develop and validate an algorithm for the prediction of lung function remaining after pneumectomy/lobectomy.

Amyotrophic lateral sclerosis transcriptomics reveals immunological effects of low-dose interleukin-2.

Amyotrophic lateral sclerosis is a fatal neurodegenerative disease causing upper and lower motor neuron loss and currently no effective disease-modifying treatment is available. A pathological feature of this disease is neuroinflammation, a mechanism which involves both CNS-resident and peripheral immune system cells. Regulatory T-cells are immune-suppressive agents known to be dramatically and progressively decreased in patients with amyotrophic lateral sclerosis.

Association between increased mortality and bronchial fibroscopy in intensive care units and intermediate care units during COPD exacerbations: an analysis of the 2014 and 2015 National French Medical-based Information System Databases (PMSI).

Background: The course of chronic obstructive pulmonary disease (COPD) is punctuated by exacerbations, most often of infectious origin, responsible for many intensive care unit (ICU) and intermediate care unit (IMCU) admissions. Our objective was to study in-hospital mortality during severe COPD exacerbations in ICU and IMCU based on the performance of bronchoscopy.

Methods: A retrospective analysis was carried out on stays in ICUs for COPD exacerbation from the French Programme for the Medicalisation of Information Systems databases for the years 2014 and 2015.

Sacubitril-valsartan initiation in chronic heart failure patients impacts sleep apnea: the ENTRESTO-SAS study.

Aims: Optimizing medical cardiac treatment for sleep apnoea (SA) in patients with chronic heart failure and reduced ejection fraction (HFrEF) is an expert Grade C recommendation based on six studies encompassing a total of 67 patients only. Whether sacubitril-valsartan (SV), a cornerstone of HFrEF medical treatment, impacts SA is unknown and requires evaluation.

Methods And Results: The ENTRESTO-SAS trial is a six-centre, prospective, open-label real-life cohort study (NCT02916160).

Apnoea-hypopnoea indices determined via continuous positive airway pressure (AHI-CPAP) versus those determined by polysomnography (AHI-PSG): a protocol for a systematic review and meta-analysis.

Introduction: To date, continuous positive airway pressure (CPAP) remains the cornerstone of obstructive sleep apnoea treatment. CPAP data describing residual sleep-disordered breathing events (ie, the CPAP-measured apnoea-hypopnoea indices (AHI-CPAP)) is difficult to interpret because it is an entirely different metric than the polysomnography (PSG) measured AHI gold standard (AHI-PSG). Moreover, manufacturer definitions for apnoea and hypopnoea are not only different from those recommended for PSG scoring, but also different between manufacturers.

"Real-life" management of patients with severe asthma in the biologics era: Can we do better?

Background: Discrepancies exist between guidelines and real-life practice in severe asthma. Objectives: To establish profiles for severe asthma patients according to their maintenance therapies and identify unmet needs.

Methods: 2432 French lung specialists and allergists were invited to participate in a severe asthma survey between March and April 2018.

Club Cell Loss as a Feature of Bronchiolization in ILD.

Distal airway metaplasia may precede honeycombing in progressive fibrosing interstitial lung disease (ILD). The SCGB1A1 bronchiolar-specific club cell may play a role in this aberrant regenerative process. To assess the presence of club cells in the small airways of patients suffering from ILD.

Mask side-effects in long-term CPAP-patients impact adherence and sleepiness: the InterfaceVent real-life study.

Background: For some patients, Continuous Positive Airway Pressure (CPAP) remains an uncomfortable therapy despite the constant development of technological innovations. To date, no real life study has investigated the relationship between mask related side-effects (MRSEs) and CPAP-non-adherence (defined as < 4 h/day) or residual-excessive-sleepiness (RES, Epworth-Sleepiness-Scale (ESS) score ≥ 11) in the long-term.

Methods: The InterfaceVent-CPAP study is a prospective real-life cross-sectional study conducted in an apneic adult cohort undergoing at least 3 months of CPAP with unrestricted mask-access (34 different masks).

Will the asthma revolution fostered by biologics also benefit adult ICU patients?

Purpose: Asthma exacerbations are inflammatory events that rarely result in full hospitalization following an ER visit. Unfortunately, certain patients require prolonged support, including occasional external lung support through ECMO or ECCOR (with subsequent further exposure to other life-threatening issues), and some die. In parallel, biologics are revolutionizing severe asthma management, mostly in T2 high patients.
